Equilateral triangles always have 3 congruent angles, so the measure of each angle is 60
Answer:
x = ± 10
Step-by-step explanation:
- 5x² = - 500 ( divide both sides by - 5 )
x² = 100 ( take square root of both sides )
x = ± 
= ± 10
That is x = - 10 or x = 10
Answer:
So the height is 12
Step-by-step explanation:
Let W be the width
Let W- 4 be the height
W2 +(W-4)2 = 400
So: W2 -4W-192 =0
One uses the quadratic solution:
W = (4 + (16 + 4*192).5)/2 = 16
